Sendmail Upgrade, new thread

[Roger Jochem]

I'm running sendmail 8.13.6 that I rebuild from source. I got the source at 
http://filelister.linux-kernel.at/mod_perl?current=/packages/lkernAT/SRPMS .

And I'm currently running Centos 3 (now it is on subversion 3.7) on my 
machine. Any better place to get sendmail 8.13 for my distro?

Regards

Roger Jochem
